in 2008 James Molloy wrote a free tutorial that taught people how to build a UNIX like operating system from scratch in C and assembly it is called "Roll Your Own Toy UNIX Clone OS" and walks through building a real kernel step by step bootloader, GDT, IDT, interrupts, paging, heap management, filesystems, multitasking and user mode are all covered this is not just theory every chapter includes code you can compile run and experiment with in QEMU

After 3.5 years building GreptimeDB (@Greptime ), here's what I wish I knew before starting: The harsh reality: We jumped into execution without proper business validation. Our idea wasn't wrong, but we skipped the unglamorous work of talking to 50-100 potential customers first. What this cost us: 1. Chased SaaS/PLG strategies that looked good on paper but didn't match market reality for data infrastructure 2. Built features for "someday" instead of "today's customers" 3. Underestimated what it takes to build a database - it's a 5-year minimum commitment What actually worked: 1. Finding co-founders with resilience, not just skills, couldn’t have asked for a better partner than @Sunng 2. Treating everyone as adults - transparency over "protecting the team" 3. Listening to the harshest critics first The biggest lesson: Find 5-10 design partners who will run with you before writing code. The fear of "custom work" is pointless when you haven't proven PMF yet. That’s like worrying about scaling before you even have users. Building infrastructure is a long game. Snowflake spent 8 years before their IPO. MongoDB built community for 9 years before cloud revenue mattered. For data infra founders: the path is longer and messier than it looks. But find the right people, stay honest about what's working and what isn't, and keep shipping. ✊ #startups #databases #opensource #productmarketfit #founders #datainfrastructure #lessonslearned

Ten years after Rust 1.0, we need to stop thinking of it as just "systems programming." That label carries historic baggage and scares away teams who could benefit from Rust. corrode.dev/blog/foundationa… #rustlang #rust

hyper in curl needs a champion. A backing vendor or distro that wants it.❤️ Why? Memory un-safety. Is. BAD. A #rustlang HTTP backend in #curl has potential to make the internet safer. 🦀 But it needs a champion to back it, or it will go away. 🚀 seanmonstar.com/blog/hyper-i…

I regretfully completely understand Wedson's frustrations. lore.kernel.org/lkml/2024082… A subset of C kernel developers just seem determined to make the lives of the Rust maintainers as difficult as possible. They don't see Rust as having value and would rather it just goes away.

Zig 社区今天出了一个备受争议的 issue，去掉对 C++/Objc 的支持，原因是 LLVM bug 太多，想要移除它。 github.com/ziglang/zig/issue… 要知道很多人选择 Zig 就是看重了它的工具链，如果真这样了，不就是壮士割腕了嘛 news.ycombinator.com/item?id… HN上讨论也比较激烈。

经过一个月的准备，Rust Magazine 第二期发布了！这一期同样充满干货，我把两年前优化 Rust 二分查找的文章翻译成英文了，并且增加了一些 Polkadot 事故的分析和教训总结。还有今天我用 AI 给第二期生成了一个新的 Ferris 图片，还是很不错的。 rustmagazine.org/issue-2/

⚛️📋 I made an overview of the ARMv8 and x86-64 machine instructions for all the common atomic operations:
Six tables showing the machine instructions for the atomic operations on ARMv8, ARMv8.1 and x86-64, for non-atomic, relaxed, acquire, release, acquire plus release, and sequentially consistent memory ordering. The six tables are labeled: load, store, swap, fetch op, compare exchange, fence. The full contents don't fit in the alt text, but here are the main takeaways: On x86, in each table, the instructions are the same for all (atomic) memory orderings, except seqcst store using a XCHG instruction instead of a MOV, and seqcst fence using MFENCE instead of nothing. On ARM, the acquire plus release instructions are equivalent to the sequentially consistent instructions in all cases. On ARMv8, the swap, fetch op and strong compare exchange are implemented as loops using the LDXR and STXR instructions. But on ARMv8.1, they are all implemented as a single instruction. On x86, fetch op is implemented with a lock prefix for some operations, and as a CMPXCHG loop for some others.

🦀 This code compiles (and runs without panicking). 10 points if you can figure out how. 😁
fn main() { let x = |_| Some(1); let (|x| x) = match x(..) { |_| Some(2) => |_| Some(3), |_| _ => unreachable!(), }; assert!(matches!(x(..), |_| Some(4))); }

终于发现 rust-analyzer 为什么某些时候不能分析某个文件了，是因为这个文件只在特定 feature 下有效，一个解决方式就是把 rust-analyzer.cargo.features 改成 all
